Understanding the confluence of injury and obesity in a Grade 2 obesity and above population.

OBJECTIVE: Obesity and injury are major inter-related public health challenges. The objective of this study was to explore the perceptions of injury in people with severe obesity. METHODS: A cross-sectional design was employed to capture injury perception and lifestyle habits via questionnaires. Weight (kg) and height (m) were measured by clinicians for patients attending a weight loss group program. Univariate, chi-square, ANOVA and ordinal regression analyses were undertaken. RESULTS: There were 292 participants (67.1% female), mean age 49.3 years and Body Mass Index 47.2 kg/m2 (range 30.7-91.9 kg/m2). Concern about having an injury was found in 83%, and 74.2% thought that weight would increase the likelihood of injury. A greater concern of being injured at baseline was associated with less weight loss at eight weeks (F=3.567; p=0.03). Depression, anxiety and sleepiness score were higher in those who reported greater 'Concern about having an injury'. CONCLUSIONS: People with obesity fear injury and falling, which limits their willingness to exercise. Anxiety symptoms appear to exacerbate this connection. IMPLICATIONS FOR PUBLIC HEALTH: In individuals with obesity, anxiety, sleepiness and depression are associated with a fear of being injured. Addressing fear and reducing anxiety may decrease barriers to participating in physical activity.

Obesity, lifestyle behaviours and psychological effects of the COVID-19 lockdown: A survey of patients attending a tertiary weight loss clinic.

Lockdown measures due to coronavirus-19 disease (COVID-19) have impacted lifestyle factors. This study aimed to explore whether health and lifestyle behaviours changed during the 2020 COVID-19 lockdown among patients with obesity. A specifically designed online survey and the Depression Anxiety Stress Scale (DASS-21) were administered to patients scheduled to attend a tertiary weight management service between 6 June-12 August 2020. A total of 210 participants completed the survey; mean age (SD) was 52.1 (12.5) years, 69% female and 67% Caucasian. Only 1.4% had tested positive to COVID-19. There was a statistically significant increase in weight pre- and post-COVID-19 lockdown, with no sex differences. Most (61.3%) gained weight, 30.4% lost weight and 8.3% maintained. The majority changed their overall purchasing (88.4%) and eating behaviours (91.6%). Two-thirds (64%) reported they did some form of exercise during the lockdown. Of those, exercise declined in 56.8% and increased in 18%. DASS-21 scores were positively correlated to worry about COVID-19, eating fewer core foods and eating more convenient/treat foods and negatively correlated with exercise. The results provide insights into how and why behaviour change occurs during stressful periods like the COVID-19 pandemic. Although there was variability in individual weight trajectories, on average people with obesity gained weight and changed lifestyle behaviours during the COVID-19 lockdown period. Strategies and support for people with obesity are required at these times.

Dietary adherence and program attrition during a severely energy-restricted diet among people with complex class III obesity: A qualitative exploration.

Meal replacement Severely Energy-Restricted Diets (SERDs) produce ≥ 10% loss of body mass when followed for 6 weeks or longer in people with class III obesity (BMI ≥ 40 kg/m2). The efficacy of SERDs continues to be questioned by healthcare professionals, with concerns about poor dietary adherence. This study explored facilitators and barriers to dietary adherence and program attrition among people with class III obesity who had attempted or completed a SERD in a specialised weight loss clinic. Participants who commenced a SERD between January 2016 to May 2018 were invited to participate. Semi-structured in-depth interviews were conducted from September to October 2018 with 20 participants (12 women and 8 men). Weight change and recounted events were validated using the participants' medical records. Data were analysed by thematic analysis using line-by-line inductive coding. The mean age ± SD of participants was 51.2 ± 11.3 years, with mean ± SD BMI at baseline 63.7 ± 12.6 kg/m2. Five themes emerged from participants' recounts that were perceived to facilitate dietary adherence: (1.1) SERD program group counselling and psychoeducation sessions, (1.2) emotionally supportive clinical staff and social networks that accommodated and championed change in dietary behaviours, (1.3) awareness of eating behaviours and the relationship between these and progression of disease, (1.4) a resilient mindset, and (1.5) dietary simplicity, planning and self-monitoring. There were five themes on factors perceived to be barriers to adherence, namely: (2.1) product unpalatability, (2.2) unrealistic weight loss expectations, (2.3) poor program accessibility, (2.4) unforeseeable circumstances and (2.5) externalised weight-related stigma. This study highlights opportunities where SERD programs can be optimised to facilitate dietary adherence and reduce barriers, thus potentially improving weight loss outcomes with such programs. Prior to the commencement of a SERD program, healthcare professionals facilitating such programs could benefit from reviewing participants to identify common barriers. This includes identifying the presence of product palatability issues, unrealistic weight loss expectations, socio-economic disadvantage, and behaviour impacting experiences of externalised weight-related stigma.

Delays in healthcare consultations about obesity - Barriers and implications.

BACKGROUND: The prevalence of obesity continues to rise, affecting nearly a third of Australian adults in 2017-18. The stigma and bias people with obesity (PwO) experience is one of the barriers hindering the dialogue between PwO and their Health Care Professionals (HCPs). The results from the ACTION IO Australian cohort are reported here. Identification of local barriers can inform strategies to improve access to quality obesity care within Australia. METHODS: The ACTION-IO study was an online cross-sectional survey conducted in 11 countries during June-October 2018. In Australia 1,000 community based adult PwO (body mass index ≥30 kg/m based on self-reported height and weight) and 200 HCPs involved with direct patient care (seeing ≥10 patients with obesity/month) completed the survey. RESULTS: There was a mean delay of 8.9 years from when a PwO first started to struggle with their weight, and the initial discussion with an HCP about this. HCPs acknowledged weight loss efforts in only 38.5% of their patients, although 74.6% of PwO had attempted weight loss. Most PwO (82.0%) assumed full responsibility for their weight loss. HCPs identified short appointment times (60.5%) and the cost of obesity medication, programmes and services (58.5%) as barriers to weight management conversations and weight loss, respectively. Most PwO want their HCP to raise the issue of weight with 64 % reporting finding such conversations positive and helpful. CONCLUSION: Compared to global results, Australian PwO took 3 years longer to seek medical care about their weight. Better recognition of obesity's impact and targeting barriers to care are needed.

ITM support for patients with chronic respiratory and cardiovascular diseases: a protocol for a randomised controlled trial.

INTRODUCTION: Simple and scalable strategies are needed to improve 'out-of-hospital' support and management for people living with cardiovascular disease (CVD) and respiratory disease. Text messaging via mobile phones has been shown to be effective in helping promote lifestyle change and is supported by quantitative and qualitative evidence. The aim of this study is to test the effectiveness and implementation of a 6-month text messaging support programme for people with CVD and respiratory disease as an addition to cardiac and pulmonary outpatient rehabilitation. METHODS AND ANALYSIS: Pragmatic randomised controlled trial (n=310) to test the effectiveness of a 6-month text message support programme on clinical outcomes in people with CVD and chronic respiratory disease who are attending outpatient cardiac and pulmonary rehabilitation. The study includes a nested process evaluation to inform scalability and implementation across settings. The intervention group will receive a text message support programme comprising five messages per week for 26 weeks and the control group will continue with standard care. The primary outcome is exercise capacity (6 min walk distance). Secondary outcomes include clinical measures (proportion of people meeting the Australian guideline-recommended blood pressure and cholesterol targets), lifestyle outcomes (smoking rates, achievement of national guidelines for nutrition and physical activity), quality of life, mood (Hospital Anxiety and Depression Scale), medication adherence and attendance at and completion of rehabilitation. ETHICS AND DISSEMINATION: Primary ethics approval was received from the Sydney Local Health District Hospital Human Research Ethics Committee and associated Governance committees at sites. Results will be disseminated via the usual scientific forums including peer-reviewed publications and presentations at international conferences. At its conclusion, the study will determine the effectiveness and implementation of a simple programme that aims to improve health outcomes and attendance at rehabilitation for people with CVD and chronic respiratory disease.

Beliefs about Binge Eating: Psychometric Properties of the Eating Beliefs Questionnaire (EBQ-18) in Eating Disorder, Obese, and Community Samples.

Binge eating is a core diagnostic feature of bulimia nervosa, binge eating disorder, anorexia nervosa binge/purge type, and is a common feature of "other specified" and "unspecified" feeding and eating disorders. It has been suggested that specific metacognitive beliefs about food, eating, and binge eating may play a key role in the maintenance of binge eating behaviour. The Eating Beliefs Questionnaire (EBQ-18) provides a brief self-report assessment tool measuring three types of metacognitive beliefs: negative, positive, and permissive beliefs about food and eating. This study aimed to build on past research by validating the factor structure and psychometric properties of the EBQ-18 using both a clinical and non-clinical sample. A sample of 688 participants (n = 498 non-clinical participants, n = 161 participants seeking treatment for an eating disorder, and n = 29 participants seeking treatment for obesity) completed a battery of questionnaires, including the EBQ-18 and other measures of eating disorder symptoms and relevant constructs. A subset of 100 non-clinical participants completed the test battery again after an interval of two-weeks, and 38 clinical participants completed the EBQ-18 before and after receiving psychological treatment for their eating disorder. A confirmatory factor analysis (CFA) was conducted and psychometric properties of this measure were assessed. The results of this study provide support for the three-factor model of the EBQ-18. In addition, the EBQ-18 was found to be a valid and reliable measure, with excellent internal consistency, good test-retest reliability in the non-clinical sample, and also demonstrated evidence of sensitivity to treatment in clinical samples with binge eating pathology. Receiver operating characteristic (ROC) curve analyses were used to identify optimal cut-off scores for the EBQ-18. This study provides valuable information about the utility of the EBQ-18 as a measure for use in both clinical and research settings.

HAPIFED: a Healthy APproach to weIght management and Food in Eating Disorders: a case series and manual development.

BACKGROUND: There is a high prevalence of overweight or obesity in people with eating disorders. However, therapies for eating disorders, namely binge eating disorder and bulimia nervosa, do not address weight management. Conversely, weight loss treatments for people with overweight or obesity do not address psychological aspects related to eating disorders. Thus we developed a new treatment for overweight or obesity with comorbid binge eating disorder or bulimia nervosa, entitled HAPIFED (a Healthy APproach to weIght management and Food in Eating Disorders). This paper describes HAPIFED and reports a case series examining its feasibility and acceptability. METHODS: Eleven participants with overweight or obesity and binge eating disorder or bulimia nervosa were treated with HAPIFED in two separate groups (with once or twice weekly meetings). Weight, body mass index (BMI) and eating disorder symptoms, as well as depression, anxiety and stress, were assessed at baseline and at the end of the 20-session HAPIFED intervention. RESULTS: Eight of the 11 participants completed the intervention, with diverse results. Six of the 8 participants who completed HAPIFED reduced their weight between baseline and the end of the intervention. Median scores on the Eating Disorder Examination Questionnaire for binge eating, restraint, and concerns about eating or weight and shape, were reduced in the group overall between baseline and the end of the intervention. One participant, who at baseline was inducing vomiting and misusing laxatives in an attempt to lose weight, reduced these behaviors by the end of the intervention. Three participants at baseline were undertaking episodes of compulsive exercise, and they reduced or stopped this behavior, but one participant commenced episodes of compulsive exercise by the end of the intervention. All participants who completed the intervention rated the suitability and success of HAPIFED as 7 or more out of 10 (0 = not at all suitable/successful; 10 = extremely suitable/successful). CONCLUSION: This case series supports the feasibility and acceptability of HAPIFED as a potential new treatment for overweight or obesity with comorbid binge eating disorder or bulimia nervosa. Clinical trials are necessary to examine the efficacy and effectiveness of HAPIFED. TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry (Universal Trial Number): U1111-1149-7766.

Confirmatory factor analysis and examination of the psychometric properties of the eating beliefs questionnaire.

BACKGROUND: The Eating Beliefs Questionnaire (EBQ) is a 27-item self-report measure that assesses positive and negative beliefs about binge eating. It has been validated and its factor structure explored in a non-clinical sample. This study tested the psychometric properties of the EBQ in a clinical and a non-clinical sample. METHOD: A sample of 769 participants (573 participants recruited from the university and general community, 76 seeking treatment for an eating disorder and 120 participating in obesity research) completed a battery of questionnaires. A subset of clinical participants with a diagnosis of Bulimia Nervosa or Binge Eating Disorder completed the test-battery before and after receiving a psychological treatment (n = 27) or after allocation to a wait-list period (n = 28), and a subset of 35 community participants completed the test battery again after an interval of two-weeks. Confirmatory Factor Analysis (CFA) was performed. RESULTS: CFA found a two-factor structure that provided a good fit to the data, supporting the solution presented in the development paper. Items with poor psychometric properties were removed, resulting in a 16 item measure. EBQ scores were found to correlate with binge eating episode frequency, increases in body mass index (BMI), and measures of eating disorder behaviours and related psychopathology. The EBQ was found to have excellent internal consistency (α = .94), good test-retest reliability (r = .91) and sensitivity to treatment. CONCLUSION: These findings indicate that the EBQ is a psychometrically sound and clinically useful measure.

Early Maladaptive Schemas and Cognitive Distortions in Adults with Morbid Obesity: Relationships with Mental Health Status.

Dysfunctional cognitions may be associated with unhealthy eating behaviors seen in individuals with obesity. However, dysfunctional cognitions commonly occur in individuals with poor mental health independently of weight. We examined whether individuals with morbid obesity differed with regard to dysfunctional cognitions when compared to individuals of normal weight, when mental health status was controlled for. 111 participants-53 with morbid obesity and 58 of normal weight-were assessed with the Mini-Mental State Examination, Young Schema Questionnaire, Cognitive Distortions Questionnaire, Depression, Anxiety and Stress Scale, and a Demographic and Clinical Questionnaire. Participants with morbid obesity showed higher scores in one (insufficient self-control/self-discipline) of 15 early maladaptive schemas and in one (labeling) of 15 cognitive distortions compared to participants of normal weight. The difference between groups for insufficient self-control/self-discipline was not significant when mental health status was controlled for. Participants with morbid obesity showed more severe anxiety than participants of normal weight. Our findings did not show clinically meaningful differences in dysfunctional cognitions between participants with morbid obesity or of normal weight. Dysfunctional cognitions presented by individuals with morbid obesity are likely related to their individual mental health and not to their weight.

Examining mindfulness as a predictor of weight loss - Findings from the DIABEGG study.

OBJECTIVE: Identifying individuals who are less likely to respond to a weight loss intervention allows better allocation or focus of resources to achieve better weight loss results. The current study investigated whether baseline levels of mindfulness would predict weight loss during a 12-month diet and exercise intervention. METHODS: The Five Facet Mindfulness Questionnaire (FFMQ) was administered and body weight measured, at baseline, three, six and 12 months in 140 participants with pre-diabetes or type 2 diabetes mellitus and a body mass index of ≥25kg/m2. 137 of 140 participants completed the FFMQ at baseline and were included in this study. RESULTS: There was no correlation between baseline mindfulness scores and weight loss. Mean baseline total FFMQ score was 112.2 [95% confidence interval: 109.4, 115.1] which did not change over the course of the study. Mean baseline body weight was 95.1kg (standard deviation (19.1kg)). There was a significant decrease in weight at month 12 (-3.8kg (±standard deviation 5.8kg)). This is comparable to the weight loss achieved by participants in other interventions of the same duration. CONCLUSIONS: The findings suggest that baseline dispositional mindfulness does not predict the amount of weight loss in a lifestyle (diet and exercise) intervention.

High or low intensity text-messaging combined with group treatment equally promote weight loss maintenance in obese adults.

BACKGROUND: Text-message and e-mail are emerging as potential methods for improving weight outcomes among obese individuals. The optimal volume, frequency, and timing of such interventions are unknown. This study investigated the effect of adjunct technological support on weight and psychological variables after a 3-month cognitive-behaviour therapy (CBT) group intervention. METHODS: Sixty obese adults were randomised to a CBT programme plus intensive (text-message and e-mail; CBT+ITS) or minimal (text-message only; CBT+MTS) technological support. Assessments occurred at baseline, 3-, 6-, 9-, and 15-months. Outcome variables included weight (kg), body mass index (kg/m2), waist circumference (cm), binge-eating tendencies, weight self-efficacy, and weight control cognitions and behaviours. RESULTS: CBT+ITS (n=31) and CBT+MTS (n=29) participants lost 5.2% (±1.1) and 4.7% (±1.1) of their baseline weight by 3-months, 8.4% (±1.2) and 6.4% (±1.1) by 6-months, 9.6% (±1.3) and 6.4% (±1.3) by 9-months, and sustained a 7.5% (±1.3) and 5.1% (±1.3) loss at 15-months, respectively. There were no significant differences between intensive and minimal support, however, the CBT+ITS group showed a marginal advantage across all anthropometric measures. CONCLUSIONS: A low intensity text-message support programme is just as effective as higher intensity technological support for maintaining weight loss in obese adults. This represents a low-cost means of aiding weight loss maintenance without reliance on extended face-to-face treatment.

Comparing cognitive behavioural therapy for eating disorders integrated with behavioural weight loss therapy to cognitive behavioural therapy-enhanced alone in overweight or obese people with bulimia nervosa or binge eating disorder: study protocol for a randomised controlled trial.

BACKGROUND: Around 40 % of individuals with eating disorders of recurrent binge eating, namely bulimia nervosa and binge eating disorder, are obese. In contrast to binge eating disorder, currently there is no evidence base for weight management or weight loss psychological therapies in the treatment of bulimia nervosa despite their efficacy in binge eating disorder. Thus, a manualised therapy called HAPIFED (Healthy APproach to weIght management and Food in Eating Disorders) has been developed. HAPIFED integrates the leading evidence-based psychological therapies, cognitive behavioural therapy-enhanced (CBT-E) and behavioural weight loss treatment (BWLT) for binge eating disorder and obesity respectively. The aim of the present study is to detail the protocol for a randomised controlled trial (RCT) of HAPIFED versus CBT-E for people with bulimia nervosa and binge eating disorder who are overweight/obese. METHOD/DESIGN: A single-blind superiority RCT is proposed. One hundred Brazilian participants aged ≥ 18 years, with a diagnosis of bulimia nervosa or binge eating disorder, BMI > 27 to < 40 kg/m(2), will be recruited from both community and clinics and individually randomised to a therapy arm. Five groups of ten participants will receive the experimental intervention (HAPIFED) and the other five groups of ten the control intervention (CBT-E). Both therapies are manualised, and in this RCT will comprise 1 individual session and 29 office-based group sessions over 6 months. Assessment points will be at baseline, end of therapy, and 6 and 12 months after end of therapy. The primary outcome of this intervention will be reduced weight. Secondary outcomes will be improved metabolic indicators of weight management, reduction in eating disorder symptoms including improved control over eating, improved adaptive function, physical and mental health-related quality of life, and reduced levels of depression and anxiety. DISCUSSION: This study will be the first to investigate a psychological therapy that aims to assist weight management in people with co-morbid overweight or obesity bulimia nervosa as well as with binge eating disorder. It will have the potential to improve health outcomes for the rapidly increasing number of adults with co-morbid obesity and binge eating disorder or bulimia nervosa.

The comorbidity between eating disorders and anxiety disorders: prevalence in an eating disorder sample and anxiety disorder sample.

OBJECTIVE: To investigate the prevalence of comorbid eating and anxiety disorders in women presenting for inpatient and outpatient treatment of an eating disorder and women presenting for outpatient treatment of an anxiety disorder. METHODS: The prevalence of comorbidity was investigated from a sample of 152 women, which included 100 women presenting for treatment of an eating disorder and 52 women presenting for treatment of an anxiety disorder. RESULTS: Of women presenting for treatment of an eating disorder, 65% also met criteria for at least one comorbid anxiety disorder; 69% of these reported the onset of the anxiety disorder to precede the onset of the eating disorder. Of the anxiety disorders diagnosed, social phobia was most frequently diagnosed (42%) followed by post-traumatic stress disorder (26%), generalised anxiety disorder (23%), obsessive-compulsive disorder (5%), panic/agoraphobia (3%) and specific phobia (2%). We also found that 13.5% of women presenting for anxiety treatment also met criteria for a comorbid eating disorder. Furthermore, 71% (n = 5) reported the onset of the anxiety disorder to precede the onset of the eating disorder. DISCUSSION: The results of this study suggest that the prevalence of eating and anxiety disorder comorbidity is high. The present research should improve the clinical understanding of the comorbidity between eating disorders and anxiety disorders. In particular, it is anticipated that this research will have significant aetiological and therapeutic implications especially with regard to improving the clinical effectiveness of psychological treatments for eating disorders and highlighting the importance of screening for eating pathology in the clinical assessment of anxiety disorders.

The co-morbidity of eating disorders and anxiety disorders: a review.

OBJECTIVE: To critically review the literature examining the co-morbidity between eating disorders and anxiety disorders. METHOD: A review of the literature on the co-morbidity between anorexia nervosa, bulimia nervosa and eating disorders not otherwise specified and the anxiety disorders of OCD, PTSD, social anxiety, GAD, panic and agoraphobia. RESULTS: Of the empirical studies undertaken, it is clear that anxiety disorders are significantly more frequent in subjects with eating disorders than the general community. Researchers have shown that often anxiety disorders pre-date eating disorders, leading to a suggestion that early onset anxiety may predispose individuals to developing an eating disorder. To date however, the research presents strikingly inconsistent findings, thus complicating our understanding of eating disorder and anxiety co-morbidity. Furthermore, despite indications that eating disorder prevalence amongst individuals presenting for anxiety treatment may be high, there is a distinct lack of research in this area. DISCUSSION: This review critically examines the available research to date on the co-morbidity of eating disorders and anxiety disorders. Some of the methodological limitations of previous research are presented, in order to highlight the issues which warrant further scientific investigation in this area.
